Patented Shadow Drive™ technology keeps you in control, even when autopilot is engaged

With a complete package designed for powerboats and sailboats, Garmin brings an advanced marine technology to the boating public that was once only available for commercial boats. The Reactor 40 autopilot series is simply the most responsive autopilot system we have ever offered.

Reactor 40 autopilots are very versatile. Both powerboat and sailing features are available in all corepacks, including heading hold, wind hold, tack/jibe, step turns and more; simply pick the autopilot that’s compatible with your existing steering system.

The Reactor 40 hydraulic autopilot corepack is ideal for all types of hydraulically steered powerboats — inboards, outboards, stern drives and diesels — or hydraulically steered sailboats. This robust unit gives powerboat users an easy-to-use autopilot system to rely upon for navigation. With its solid-state 9-axis AHRS, Reactor 40 mounts nearly anywhere, in any orientation and requires minimal commissioning. Our patented Shadow Drive technology gives boaters the security of knowing they maintain control, even when relying upon the autopilot.

With its advanced solid-state 9-axis solid-state 9-axis AHRS, you can mount Reactor 40 nearly anywhere, in any orientation. In addition, this new system greatly minimizes heading error, course deviation, rudder movement and power consumption while providing a comfortable ride for all on board.

This amazing autopilot actually reacts to the sea to hold your course. Even when the boat is pitching and rolling, you can remain confident that the Reactor 40 autopilot will keep you on your desired course.

All autopilots require commissioning and calibration — all of them. We know you just want to get on the water, so we made this process as fast and easy as possible. That’s the power of simple.

Combined with a compatible Garmin networked chartplotter, you can have full control of Reactor 40 from wherever you are on the boat. In addition to holding its course in virtually all weather and wind conditions, the system can smoothly perform a variety of preprogrammed trolling and search procedures. Plus, with a compatible Garmin networked chartplotter and BlueChart® g2 Vision® charts (sold separately), you gain optional features such as Auto Guidance , which automatically steers GPS paths.

The Reactor 40 autopilot features patented Shadow Drive technology. This gives you the security of knowing you maintain control, even when the autopilot is engaged. The Shadow Drive system automatically disengages the autopilot if the helm is turned, giving you the freedom to maneuver the boat. The autopilot automatically re-engages when you hold a steady course.

Reactor 40 is operated using up to 3 GHC™ helm control units. GHC communicates with the autopilot system via your NMEA 2000® network, so autopilot heading data can be shared easily with other devices. This enables MARPA and chart overlay when connected to a Garmin chartplotter. An optional handheld wireless remote control is also available; however, for the highest level of convenience, control GHC using a compatible quatix® 3 or quatix 5 marine multisport smartwatch.
